The most misspelled word in the English language has to be 'referrer'.
At least on the Internet where the misspelling 'referer' occurs 25%
more often than the correct spelling. For this we can thank a computer
scientist named Phillip Hallam-Baker.

In the early 1990s, when specifications for the Web were being hammered
out, Hallam-Baker suggested a 'referer' value to keep track of what Web
page a user clicked on to land on another Web page. The spelling has
stuck since then, but let's not be too hard on him.

English spelling has never been consistent, which explains the prevalence
of spelling bee competitions in English, unheard of in other languages.
For example British English uses 'traveller', while American English goes
with 'traveler'. But even the doubling of consonants is not consistent.
Consider British 'enrol' vs. American 'enroll', while both languages go
with 'comforter' and 'transmitter'.

No wonder engineers feel more at ease with computer languages over human
languages.
This week's words appear to be misspelled, but aren't. Watch out -- your
spellchecker is going to go ballistic.
